To make its big reveal, she wrote on Instagram about the "piece of pop candy":

"After a year of peaks and valleys (remember, it's all a journey), I wanted to end 2017 with a fun, triumphant piece of pop candy. Just think of it as a glam little stocking stuffer from me to you. 'Hey Hey Hey' is one of my favorite songs from 'Witness' and for me, it embodies the fighting spirit I always want you to be able to find within yourself, and to see in me.
So ho, ho, ho; and hey, hey, hey; and happy holidays."

The Molly's Game actress weighed in on the situation, as she noted on Twitter:

On the 6th day of Perezmas, pop culture gave to us… 6 messy custody battles!

When celebrity parents get divorced, we can expect a draaaawwwwwn out legal fight over who gets the kiddos — and these disputes usually lead to the airing out of some VVV dirty laundry.

Angelina Jolie and Brad Pitt's custody war, for example, has been so intense it rolled over into 2017. The couple may have taken their contentious battle out of the headlines, but they have still yet to reach a permanent agreement.

Of course, the late Brangelina isn't the only power couple to duke it out with all the intensity of that Mr. & Mrs. Smith domestic fight scene — see more of 2017's messiest celeb custody battles (below)!
